MediaPortal Version: 0.2.3.0 Stable Release
Windows Version: Windows XP Prof SP2 32bit
CPU Type: AMD Athlon X64 Dual Core 4800+
Memory: 2GB
Motherboard Chipset: nForce4 Ultra

I'm great ffdshow fan and I prefer to use it to decode everything:

I'm using latest ffdshow tryouts

Every time I'm starting video playback using MediaPortal internal player flip video option in ffdshow is inverted :o

For example let's uncheck it, then start playback. And volia - it's checked and output video is fliped! Let's stop playback and start it again (or just select different file) - volia, it's unchecked again :S

In other DirectShow-based multimedia players everything is fine. I've checked it into
1) Windows Media Player 6.4 (Start->Run->mplayer2)
2) Media Player Classic
3) Light Allow
4) GOM PLayer

Every time (except GOM player, wich add some internal filters) I got 100% same filtergraph (checked twice):
[Haali Splitter]->[ffdshow video decoder]->[renderer] for video part and
[Haali Splitter]->[ffdshow audio decoder]->[reclock] for audio part

Disabling reclock doesn't help.

ANY IDEAS?

MediaPortal might be modifying the registry value that controls that flip option. Ask the MediaPortal devs.

no ;)
I perform hex-editing in ffdshow.ax and replaced all flip by fl1p - problem still exists. So it's not just registry key...

Can anybody at least check - does this issue reproduce? Maybe it's my own local problem...

Ok, I have reproduced this bug onto my office PC...
This is same topic onto MediaPotral forum (http://forum.team-mediaportal.com/codecs-external-players-55/strange-flip-behavior-using-ffdshow-35689/)

I can reproduce. I'll look into it when I have time.
